• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - ((hinh trong) OR (anh truong)) ((cao thong) OR (cao phong)) thong dan chat ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - ((hinh trong) or (anh truong)) ((cao thong) or (cao phong)) thong dan chat ban*.
